Abstract
The present invention relates to a Time Compression Multiplexing (TCM) technique for transmitting three consecutive television picture signals from a television picture source during the time period normally used to send one television picture signal. More particularly, three consecutive lines or fields from a TV signal source are compressed into an ordinary line or field period, respectively, by sending one line or field as is, but time compressed, in one portion of a line or field period and sending two other lines or fields as differential signals, also time compressed, to occupy two separate and different portions of the same line or field period as is used by the first one line or field. With such technique it is possible to send three consecutive line or field signals from each of three separate colocated or non-colocated TV sources on a Time Division Multiple Access (TDMA) basis.
